A TTORNEY Patented May 6, 1941 WINDOW SASH Arthur E. Waterman, Fort Atkinson, Wis., assignor to J ames Manufacturing Company, Fort Atkinson, Wis., a company of Wisconsin Application July 13, 1938, Serial No. 218,922

2 Claims. (Cl. 189--76) The present invention relates to a window sash Vstructure which is specially adaptable for farm buildings particularly when used as a storm sash.

The principal object of the present invention is to provide a sash frame the side, top and bottom members of which are formed rectangular in cross section from sheet metal the edges of the sheets being folded and securedr together preferform a novel an-d eicient supporting memberk for the panes of glass which readily adapts itself to the use of putty or the like.

Another object of the present invention is to provide novel and inexpensive means whereby the sash may be detachably supported hingelike at its ltop in combination with locking and adjusting means at its bottom.

To these and other useful ends my invention consists of parts, combinations of parts, or their equivalents, as hereinafter set forth and claimed and shown in the accompanying drawing in which:

Fig, 1 is a transverse vertically sectioned View of my improved sash mounted in a window frame so as to act as a storm Window, the sash being sectioned on line I--I of Figure 2.

Fig, 2 is a rear elevation of my improved sash having the panes of glass suitably secured therein a portion of one pane being removed in order to expose to view the manner of spot welding the frame folds.

Fig. 3 is an enlarged fractional section taken on line 3-3 of Figure 2.

Fig. 4 is an enlarged fractional section taken on line 4-4 of Figure 2.

As thus illustrated, the side members of the sash frame are designated in .their entirety by reference character A the top member by reference character B and the bottom member by reference character C. The mullions are designated in their entirety by reference character D.

Referring now to Figure 4 which should be understood as illustrating a .transverse section of members A and B as Well as member C. Numeral 8 designates the rear wall of the frame members and 9 the outside edge wall of these members. Numeral I0 designates the front wall and I I the inside wall.

Member I0 extends inwardly as at I2 past member II as illustrated, terminating as a-t I3 at which point it is bent slightly rearward and extending further for a short distance terminating as at I4.

Member II is bent inwardly at a right angle as at I5 terminating as at I3 forming member I6 which contacts member I2 and is secured thereto preferably by closely spaced spot welding as at 20. Thus it will be seen that I have provided frame members which may be rectangular in cross section and having inwardly extending portions, the inner edge being adapted to form a rest for the window pane I'I, the edge being positioned whereby the pane will be held a slight distance above member IB, thus when the panes are placed into position, their outer edges on opposite sides may be embraced by putty I8.

Thus it will be seen that the pane is provided with a semi-flexible support which will yieldingly contact the pane and that the pane edges will be surrounded by the putty forming a strong sealed joint having a pleasing appearance from the front or rear.

One of the advantages of the present invention is that the frame will be very rigid because the edges of the metal from which it is formed are securely fastened together. The ends of the frame members are preferably mitered and welded together electrically. Thus the frame members will have the same strength and rigidity as if formed from a rectangular seamless tube. The point I4 upon which the pane rests is clearly flexible so the sharp edges for their lengths will snugly contact the pane thus to preclude the possibility of exposing the putty to View from the front of the sash because when the proper amount of putty is placed on members I4, I6 and 23 and the glass is pressed down firmly, the putty will ooze in opposite directions until it is cut free or separated at the sharp edges of members I4 and 23.

In Figure 2 I illustrate a portion of one of the panes cut-away thus to expose to view members I4 and I6 and points 20.

The mullions are clearly illustrated in section in Figure 3. 'Ihey consist of flat bars bent into U-shapes as at 2| and folded back outwardly as at 22 forming inwardly extending anges 23 which also extend slightly rearwardly thus to form sharp edged seats upon which the window pane may rest similar to that shown in Figure 4 thus the panes may be sealed to the mullons with putty in a mannerV similar to that shown in Figure 4.

Members D are preferably welded together at their intersecting pointsr and the ends are preferably welded to the fra-me members A, B and C thus by scrutinizing Figures 2, 3 and 4 it will be seen that I have provided a Very neat, light, simple and strong window sash which obviously may be made in various sizes to accommodate various numbers and sizes of window panes.

-Frame member B is provided with spaced slots 24 and when the sash is mounted as in Figure 1, nat pieces of steel 25 are secured to the bottom of strips 26, the inner ends being bent upwardly as at 2 so as to prevent the sash from accidentally becoming disengaged and 'provide a suitable hinge for the sash. It will. be

seen that by moving the sash to a proper position it may be unhooked from member 25.

Near the bottom of members A I secure brackets 3i) having hingedly connected thereto bars 3I, these bars being provided with a number ofv notches 32 and extending through a slot provided in bracket 33 which is mounted on the Vhooked into a bracket 35. These locking and Yadjusting means are too well known to require further description and are shown as one ofV the many means that may be used for locking the sash in its open or closed position.

Referring to Figure 3. It will be noted that a slight opening as at 28 is provided thus there will be slight flexibility in the mullions to accommodate unequal expansion and contraction between the window panes and the sash members thus to prevent the pane from breaking loose from the putty and the putty from breaking loose from the mullions or frame members.

Having thus shown and described my invention, I claim:

1. A Window sash of the class described, having side and end members forming a rectangular frame, said side and end members being formed from sheet metal strips into rectangular in cross section members their ends being secured together forming the frame, the front Walls of said frame members extending inwardly a short distance past the inner walls of the frame and then being bent at a slight angle rearwardly and extending further for a short distance to thereby form a yielding sharp edge seat for contact with thev window pane, the inner wall of the frame members being bent inwardlyv at right angles and parallel to said rst extended edges and terminating at said rst bend and being rigidly secured to said rst edges.

2. A' device ask recited in claim l including; mullions secured to said frame and being formed fromrelativel-y thin flat steel strips into U- shaped" channels, inwardly and rearwardly extending flanges ony the free edges of said channels andi being adapted to form yielding sharp edged 'seats for contact with the window pane.
